1. Click the Edit Target button to edit the target. See Figure 15.
Note that the target response is a combination of a graphically editable curve and the cross-over
filters that are edited separately.
• Adjust the curve by clicking on a point and dragging it to a new location.
• Double-click on a point to erase that point.
• Double-click anywhere on the red line to add a new point.
The target curve should be a flattened-out version of the original system, centered around 0 dB.
Although a completely flat response would theoretically be ideal, in normal rooms it is customary
to have a certain bass boost and a certain roll-off at high frequencies. Too much boost at certain
frequency regions may also excite non-linear distortion.
2. Adjust the cross-over settings and enable/disable the cross-overs, as desired.
It is normally convenient to use the cross-overs to make sure that speakers are not driven outside
their linear regions. The cross-over curves are included in the overall target response displayed in
red.
Blue plot = average magnitude response.
Red plot = suggested target curve.
